At the chain’s home improvement store in Abilene, Luthy works part-time, looking spiffy in his Lowe’s vest with Charlotte in tow. She looks professional in her own store coat, which her master sewed for her.

"Instead of medicine, I have Charlotte," the veteran who served in Qatar and Uzbekistan told CBS affiliate KTAB-TV. After multiple knee surgeries, the military ruled he couldn’t re-enlist, Luthy said.

So when he applied at Lowe’s, he took Charlotte with him — and no one there had a problem with that.

The manager he spoke to said, “Absolutely... We’ve got service dogs at work throughout Lowe's,” Luthy recounted.
